Slack Reviews & Product Details

Slack Overview
What is Slack?

Slack is the top choice for teams to communicate. It provides a virtual workspace that helps teams maintain open communication in a business environment. With Slack, users can host voice and video calls with up to 15 participants and even screen share with a desktop app, empowering better user interaction. Slack also supports options for private and group sessions, and one of its best features is Slack Huddles–an informal meeting space that lets you directly talk to your channel where you can share screen side by side with your team. The platform integrates well with Dropbox, Google Drive, and Trello as well.

"Most Convenient Workspace Collaboration Tool"
What do you like best about Slack?

Easy to use, and easy to track message/threads that require your attention. Easy to sync up with teammates in a huddle session, in which one can share screen and others can draw on host`s screen from remote.

What do you dislike about Slack?

I wish I could customize the UI/theme, like dark theme and bigger font, Aria style. I wish I can integrate with calendar app easily to setup focus time, or no noise time etc.

What problems is Slack solving and how is that benefiting you?

Team collaboration on either text or multi-media format. That helps sync up within the team, better collaboration with remote team members.
